Product Description

The B Series LED luminaire is a dust-ignition-proof choice for marine and hazardous applications. They can be used in locations where moisture, dirt, dust, corrosion and vibration may be present, or areas where wind, water, snow or high ambient can be expected.

Class II, Division 1 covers areas where combustible dust is present continuously or intermittently during normal operation — typical applications include grain elevators, flour and feed mills, coal handling, and metal-powder plants.
